Question
Which of the following would lead to an increase in the measured final temperature in the calorimetry of neutralization reactions using a coffee cup calorimeter?
Select one:
O a. Thermometer was not read right away
O b. Smaller Coalorimeter
O c. Calorimeter was punctured with a small hole
O d. Smaller number of moles of limiting reactant
A coffee-cup calorimeter was calibrated using 10.0 mL of 0.100 M HCl and 2.00 mL of 0.300 M NaOH (AH° neutralization=-55.8 kJ/mol). The reaction mixture had 0.300°C
increase in temperature. Using the same calorimeter, 5.00 mL of 0.250 M HNO3 was made to react with 7.00 mL of 0.100 M NaOH. A temperature rise of 0.320° C was
observed. What is the AH° reaction of this reaction?
Select one:
O a. ~ +51.0 kJ/mol
O b. ~ -35.8 kJ/mol
O c.
~ +55.8 kJ/mol
O d. ~-51.0 kJ/mol
